Not strictly true. Some sort of fencing is required, but to my knowledge it doesn't have to be SFEX. lmb: can you comment? > > The primitive to use (sdb_stonith) is configured with > "stonith:external/sbd". > > But I'm on rhel6, and all stonith functionnalities have been removed by > RH, justified that > RH delivers similar fencing agents . > (remember : we already have discuss about fence_ipmilan problems > and you gave me a workaround to make it working with Pacemaker > (pcmk_host_check=none) ) > > So there is no stonith:external/sbd script available, even no more > /usr/sbin/stonith binary delivered on RHEL6. Correct, on RHEL6 we only have the fencing devices used by the rest of RHCS. Management didn't like the idea of maintaining two overlapping sets. > So do I reach a dead-end for OCFS2 under Pacemaker on RHEL6 ? On RHEL6 you're probably better off with GFS2 - at least that way you're likely to have a supported configuration eventually. But as to your specific problem, you could either use one of the RH fencing agents or re-build cluster-glue to include SFEX. _______________________________________________ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
